Data Access, Data Ownership, and Sharecropping

Kellan Elliott-McCrea (via John Gruber):

With Flickr you can get out, via the API, every single piece of information you put into the system.

Every photo, in every size, plus the completely untouched original. (which we store for you indefinitely, whether or not you pay us) Every tag, every comment, every note, every people tag, every fave. Also your stats, view counts, and referers.

Bravo.
